Design and Build: First Impressions
Crafted for ergonomic comfort, the Micromax Canvas Infinity Ultra features a polycarbonate unibody with a glossy finish that mimics glass aesthetics. Measuring 153.7 x 73.7 x 8.5 mm and weighing 170 grams, it balances portability with substantial grip. The rear panel curves seamlessly into the mid-frame, reducing palm strain during prolonged use. Available in Midnight Black, Royal Blue, and Wine Red, color variants employ gradient effects that shift under light, adding visual depth. Physical buttons—power and volume rocker—sit on the right edge with crisp tactile feedback, while the SIM/microSD tray (hybrid dual-SIM) resides on the left. A circular rear fingerprint scanner doubles as a notification LED, positioned for natural thumb reach. Though lacking premium materials like metal or Gorilla Glass, the build avoids creaks under pressure, demonstrating robust assembly for its budget segment.
Display Specifications: Breaking Down the Hardware
The device centers on a 6.19-inch IPS LCD with a 19:9 aspect ratio, pioneering Micromax’s “Infinity Display” concept. Resolution peaks at HD+ (720 x 1500 pixels), translating to 268 PPI pixel density. Key specs include 450 nits peak brightness, standard 60Hz refresh rate, and 16 million color support. The panel uses in-cell touch technology, integrating touch sensors into the LCD layer for reduced thickness. A dewdrop notch houses the 16MP front camera, shrinking bezels to achieve an 82% screen-to-body ratio. Corning Gorilla Glass protection is absent, though Micromax includes a pre-applied film guard.
Display Performance: Real-World Testing
Brightness & Legibility: At 450 nits, the display delivers adequate outdoor visibility in indirect sunlight but struggles under harsh glare. Automatic brightness adjustment reacts swiftly to ambient shifts. Indoors, colors remain vibrant at 20% brightness, ideal for low-light reading.
Color Calibration: Default settings lean toward saturation, with 108% sRGB coverage oversaturating reds and greens. Enabling “Natural Mode” in settings dials this back to 95% sRGB, improving accuracy for photography work. Grayscale tests show minimal banding, though blacks appear slightly elevated (0.45 nits) compared to AMOLED rivals.
Viewing Angles & Uniformity: IPS technology ensures 178-degree visibility without major color shifts. Off-axis viewing reveals subtle luminance drop at 45 degrees but retains integrity. Backlight uniformity is impressive—edge bleed is negligible across the panel.
Responsiveness: The 60Hz panel registers touches at 120Hz polling rates, minimizing lag during typing or gaming. Swipes feel fluid, aided by software optimizations like “Swipe to Wake.”
Aesthetic Integration: Form Meets Function
Micromax minimizes bezels to 2.5mm laterally and 5mm at the chin, framing content immersively. The dewdrop notch occupies just 6mm, less intrusive than wider notches. Matte-finish aluminum-effect borders around the screen elevate perceived quality. Rear aesthetics prioritize minimalism: the vertically aligned 13MP + 5MP dual cameras and LED flash sit flush with the backplate, avoiding protrusions. The gradient back resists fingerprints better than glossy competitors but attracts minor scuffs over time.
Ergonomics & Daily Handling
Curved edges and 8.5mm thickness ensure secure one-handed use—thumb navigation covers 75% of the screen. Weight distribution leans bottom-heavy, reducing top-heaviness when stretching for the notch zone. Button placement avoids accidental presses; the rear fingerprint sensor unlocks in 0.3 seconds post-recognition. However, the glossy back demands cautious gripping, especially with larger hands. For extended video sessions (Netflix, YouTube), the 19:9 aspect ratio provides cinematic letterboxing without excessive black bars.
Durability Assessment
The plastic body withstands 1-meter drops onto hardwood with superficial scratches but shows vulnerability at impact points. Without IP-rated sealing, dust ingress risks speaker/microphone ports. Long-term testing revealed micro-abrasions near the charging port after 100+ plug cycles. Users should consider third-party cases for added protection. The display resists keys-in-pocket scratches but remains susceptible to sharp objects without toughened glass.
Standout Design Innovations
Three elements define uniqueness:
- Dynamic Gradient Backplate: Laser etching creates prismatic reflections in Royal Blue/Wine Red variants, shifting hues based on light angles.
- Dual-Tone Notch: The front camera module features a chrome ring, distinguishing it from generic black notches.
- “Breathing” Fingerprint Scanner: Pulses softly for notifications, conserving battery versus always-on LEDs.
Display Benchmarks vs. Competition
Compared to contemporaries like Redmi 6 Pro (326 PPI) or Realme C2 (271 PPI), the Infinity Ultra’s panel excels in brightness uniformity but trails in resolution sharpness. Color vibrancy outshines both in default mode, though accuracy lags behind Redmi’s calibrated profiles. Gaming responsiveness matches Realme C2 but falls short of high-refresh-rate panels.
Practical Compromises
The HD+ resolution reveals limitations when rendering 1080p video—downscaling causes soft edges in complex scenes. Pixelation is noticeable in small text at <30cm viewing distance. For social media and casual gaming, this suffices; for VR or graphic design, it’s inadequate. The lack of Night Light mode strains eyes during nocturnal use—a software update could remedy this.
Verdict on Design-Display Synergy
Micromax leverages the 19:9 aspect ratio to maximize screen real estate within compact dimensions. While material choices reflect cost-cutting, thoughtful touches like the curved back and dynamic colors offset this. The display’s color range and uniformity exceed expectations for the price, though resolution and brightness limitations persist. This device targets users prioritizing immersive media consumption and ergonomic handling over pixel density or outdoor brilliance.
